Keramischer Wabenkörper

摘要

A ceramic honeycomb structural body having a plurality of open-ended cells defined by cell walls, wherein a reinforcing portion is formed in each corner part of an open-ended cell existing in a second zone outside a first zone inclusive of a center on a plane perpendicular to the open-ended cells. The reinforcing thickenings of the walls at the corners of the cells improve the mechanical strength of the ceramic honeycomb body.
